NUT-LOCK.

SPECIFICATION formingpart of Letters Patent No. 637,710, dated November21, 1899.

Application filed September 26, 1 898. Serial No. 691,927. (No model.)

To all whom t may concern:

Be it known that I, JOHN W. B. COOK, a citizen of the United States,residing at St. Louis, State of Missouri, have invented certain new anduseful Improvements in Nut-Locks, of which the following is a full,clear, and exact description, reference being had to the accompanyingdrawings, forming a part thereof.

My invention relates to improvements in 1o nut-locks; and it consists inthe novel combination and arrangement of parts, as will be hereinafterparticularly described, and pointed out in the claims.

In the drawings, Figure l is a front eleva- I5 tion of my completeinvention. Fig. 2 is a side view of the same. vation of the lock proper.Fig. 4 is a front elevation of a modification of my invention, and Fig.5 is a side View of the same.

2o The object of my invention is to provide a simple, durable, andeffective nut -lock in which the ordinary bolt and nut are employedwithout the slightest alteration or modification, and, further, is ofsuch a nature that z 5 the nut may be removed from the bolt withoutdestroying or injuring any of the parts in the slightest manner.

Referring to the drawings, l represents an ordinary angle-bar orfish-plate which is em- 3o ployed in connecting the meeting ends of therails of a railroad-track; 2, the bolt, which is passed through theseveral parts, and 3 the nut, which is screwed upon the screwthreadedend of the bolt, all of which is of the usual 3 5 construction.

Myinvention is constructed in the form of a washer and is adapted toencircle the bolt and be interposed between the vertical outer surfaceof one of the angle-bars and the inner 4o engaging face of the nut,whereby the ordinary washer may be dispensed with.

The nut-lock proper is composed of a single piece of metal and is bentor otherwise formed from a bar which is rectangular in cross-section,the same being formed in the shape hereinafter described by a suitablemachine designed for the purpose.

4 represents the nut-lock, which is of a uniform size throughout itsentire length and 5o is provided with a curved upper portion 5,

Fig. 3 is a'front elewhich is adapted to freely encircle thescrewthreaded end vof the bolt 2, the free end of said curved portionterminating adjacent to the lower horizontal extension 6, which operatesto prevent the lock from being turned when the nut is brought againstthe same and, further, acts as a lock or fastening device when the nutis properly turned to thoroughly secure the several parts together. Thelower horizontal extension 6 of the nut lock is 6o slightly bent at anangle to the remaining or A 'curved portion 5, or in such a directionthat the same will be out of contact with the anglebar l when the saidnut-lock is placed in its proper position upon the bolt, whereby whenthe nut is screwed upon the bolt and the inner vertical dat su rfacecomes in contact with the outer vertical surface of said extension thelatter will be forced inwardly or against the vertical surface of theangle-bar, the said 7o y nut being turned until the parts are rmlysecured together and one of its flat sides is parallel with the upperstraight surface of said extension, when the latter by its own nature (aspring) will move outwardly or from its depressed position and securelylock the nut against rotation in the opposite direction.

It is to be observed that the lower horizontal straight extension 6 ofthe nut-lock extends beyond the curved portion 5 of the same in 8o orderto prevent the nut from turning the said nut-lock in a direction toremove the latter from the bolt.

Should it be desired to remove the nut from the bolt for any reason, thesame can be ac- 8 5 complished in a Very simple and convenient manner.Formed in the outer vertical surfaces of the curved portion and thehorizontal extension of the nut-lock adjacent to the ends of the sameare grooves 7, which are ar- 9o ranged at an angle and on a line withone another andare adapted to receive the end of a suitable hand tool orimplement :flush with the outer surfaces of the nut-lock, whereby afterthe nut has been slightly turned to the right the said extension will beforced inwardly or against the angle-bar, and thus the nut will be freeto be turned in the reverse direction for removingthe same from thebolt.

From an inspection of the drawings it will loo n 30 ter operating to-lock the nut, as :in .the pre,` i
